Currently non-US economies represent 82% of the world. Non-US Internet users represent 90%. Non-US people are 95% of the world.
And the US is not growing its share of world GDP, Internet usage, nor population.

I'd argue that the "wealth" (aka "valuation") of many US Internet companies is increasingly dependent on a larger user base instead of a richer one. Facebook paying $16B to acquire Whatsapp (and its 450M decidedly non-wealthy users) comes to mind.
You can remove France from that very short list. It has been revealed that France does its own surveillance on its own population, and exchanges this data with the USA through the Lustre program [0], revealed in a German newspaper [1].
What's even more interesting is that the USA has little penetration in Africa's surveillance, but due to its history, France has a very strong presence there: Most of the intercontinental cables end in France, and the biggest telecom operator (Orange, ex France Telecom) is present in pretty much in every french-speaking country in Africa, along with Bull-Amesys, the one that installed the shiny surveillance toy for Al-Assad.
If the USA wants intelligence on Africa, signing a deal with France was a very important move. The french press not saying anything about it says everything about the level of independence and journalism.

I'm not saying that it's good practice to do what the U.S. did and I am appalled. However, they will not lose 95% of the markets, at least not now. There is currently no country with the capacity to generate as many new ideas into businesses, and the U.S. is roughly 25% of the worlds entire economy. Hell, just California is the worlds 7th largest economy.
Further, you don't think the other large nations (by economy), such as Japan, China, India, Russia, the U.K. are not doing/going to do the same thing (I omitted Germany and France since they seem to not wire tap.. Not necessarily true).
Business wouldn't and wont be cut 95%, I am pretty sure most countries are grateful the U.S. is setting precedent and will request them to issue warrants on their citizens.
